30=(10*3*x)/2
*2 *2
60=10*3*x
60=30x
60/30=30x/30
2=x
Step-by-step explanation:
40 days = 15 boys
1 day = 15/40 = 3/8
therefore,
30 days = 3/8 × 30
= 11.1/4 boys or 11.25boys
You will find the side by 28 ÷ 4 = 7 ft because a square has 4 equal sides.
Then we will do side × side to find the area of a square, so 7 × 7 = 49 ft²
So the answer is 49ft²
From the information we have, we can conclude that this quadrilateral is a rectangle. The reason behind this is because rectangles have two sets of parallel sides, which makes them different from squares.

I would use the quadratic equation for this.
